--------------------------------------
Summary: Support execution with static resources (Flip-6): E.g.
spreading tasks across available set of TMs
Key: FLINK-11815
URL: https://issues.apache.org/jira/browse/FLINK-11815
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.7.2, 1.6.4
Reporter: Piotr Nowojski
FLIP-6 code path changed how tasks are distributed across the cluster which is
causing problems in some scenarios. This issue intends to improve this.
Known issues:
1. key groups are currently assigned randomly, ignoring their size. Previously
larger key groups were evenly spread around the available task managers
2. if task slots are registered before slot request, the code have a tendency
to group requests together on the same machine because we are using a
LinkedHashMap
